# clatd(8) integration in interfaces(5)

# To use just copy this script to /etc/network/if-up.d/ and
# /etc/network/if-down.d/

# To configure which connection should include clatd the file
# /etc/default/clatd is used. To enable clatd on a interface
# include the interface in CLATD_IFACES (space sperated)

# For logical intefaces (i.e. wpa_supplicant integration) you
# can also set one CLATD_LOGICAL. See interfaces(5) for details.
